Wait, what?!?! How come the question implies otherwise? Can someone please clarify this for me? The general points for a response would be greatly appreciated. :D

But if the speed of light was constant, why would it matter if the aether existed or not?

But how does the constancy of c (speed of light) explain the null result of the Michelson-Morley experiment (i.e. non-existence of the aether)?

How did Einstein's Theory of Special Relativity explain the result of the Michelson-Morley experiment? (4 marks, 2001 HSC) Could someone help answer this question? I'm not really sure how the Einstein's theories and the MM experiment are interconnected. Thanks!

Re: HSC 2015 3U Marathon Find the zeroes of the polynomial P(x) = 2x^3 - 13x^2 + 22x - 8, given that one zero is the product of the other two.

Since P=VI and V=IR, we get Power loss = I^2R and find that a low current results in less power loss. Thus, electricity is stepped up to high voltages since according to P=VI, a high voltage results in a low current. But, if I=V/R is substituted into the P=VI equation, giving us...

Shouldn't eddy current still form on R because it's a solid conductor? They'll be much smaller than the ones in Q, but they'll still slow down the magnet. Is this right?

Can someone please explain why the answer is C, not B?

re: HSC Chemistry Marathon Archive But why can't electrons flow through the salt bridge? How does the physical separation of electrodes lead to increased lifespan of battery? Sent from my iPhone using Tapatalk

re: HSC Chemistry Marathon Archive Couple of questions on galvanic cells: - Why do electrons flow via the external wire, not via the salt bridge? - Why do the anode and cathode have to be physically separated?

I'm doing Latin this year too! Does anyone have any half-yearly/trial papers to share around? I have a few.

Does anyone have resources for 1984 & Metropolis, or just on Module A in general? Thanks in advance :)

Why is that the case?

There seems to be an error on the 'HSC Notes and Textbooks' forum, as old posts where people were selling resources has become unavailable. It says that we need a password to access it. Could someone look into this?

Hi, could you send sample notes on Robert Gray's poetry to danthetan123@gmail.com? Thanks.

How should you respond to this question, in regards to Gray's poetry? "To discover is to be enlightened. Do you agree?" For me, this question was really challenging because I thought that discovering and enlightenment are essentially the same thing, so there's nothing to talk about. Does...

Bump!
